Summary[edit]

Description
English: This rock is nicknamed "Transvaal jade", but it is not jade. "True" jade refers to either nephrite or jadeitite metamorphic rocks. Transvaal jade is a greenish garnetite, a crystalline-textured metamorphic rock composed of hydrogrossular garnet - this sample is cryptocrystalline. Some specimens have black bands of chromitite.

Stratigraphy: unrecorded/undisclosed (but possibly from the Critical Zone, Western Lobe of the Rustenburg Layered Suite, Bushveld Complex, Paleoproterozoic, ~2.05 Ga)

Locality: unrecorded/undisclosed site in Transvaal, South Africa (but possibly from old diggings on the grounds of a Lonmin platinum mine, apparently at or near Buffelsfontein, Bonjanala Platinum District Municipality, North West Province, South Africa)
